Electrochemical Impedance Analyzer
Manufacturer: Princeton Applied Research
Model: VersaSTAT3-450
Application:
This instrument is a voltage and current control and measuring device. It is capable of maintaining the potential of the working electrode with respect to the reference electrode. It can also keep the current through an electrolytic cell. It is fundamental to investigations of electrochemical reactions and phenomena by various techniques, which the patterns of the potential or the current over time are different.
